| Logic HIGH | The higher of two voltages in a digital system with two logic levels. |
| Logic LOW | The lower of two voltages in a digital system with two logic levels. |
| Nucleus | The massive, stable part of the atom that contains both protons and neutrons. |
| Ohms | Unit of resistance. Value of one ohm allow current of one ampere with potential difference of one volt. |
| Ohm’s Law | In electric circuits, I=V/R. |
| Oscilloscope | A piece of test equipment used to view and measure a variety of different waveforms. |
| Parallel Circuit | One that has two or more branches for separate current from one voltage source. |
| Period | The amount of time required for one complete cycle of a periodic event or waveform. |
| Proton | Particle with positive charge in the nucleus of an atom. |
| Simulation | Testing design function by specifying a set of inputs and observing the resultant outputs. Simulation is generally shown as a series of input and output waveforms. |
| Resistance | Opposition to current. Unit is the ohm. |
| Series Circuit | One that has only one path current. |
| Sine Wave | One in which amplitude varies in proportion to the sine function of an angle. |
| Square Wave | An almost instantaneous rise and decay of voltage or current in a periodic pattern with time and with a constant peak value. |
| 555 Timer | TTL-compatible IC that can be wired to operate in several different modes, such as a one-shot and an astable multivibrator. |
